The incidence of atrial fibrillation in patients with coronary artery disease

The incidence of atrial fibrillation in patients with coronary artery disease Dušan Miljković Health Center Varvarin Introduction: Atrial fibrillation(AF) is the most common and widespread long-term cardiac arrhythmia in adults.The aim was to examine the frequency of AF in ambulatory patients with coronarography confirmed coronary disease. Methods: The trial included 264 patients (57.5±9.4 years) with coronary artery disease, 204(77,3%) men and 60(22.7%) women. All clinical examinations were performed, continuous ECG control, laboratory, echocardio-graphic diagnostics and coronarography. Results: The incidence of AF in patients with coronary artery disease is 9.85%, paroxismal AF 4.17%, persistent and permanent AF 5.68%. There was no significant difference in the incidence of singl-vessel disease (p>0.05), two-vessel disease (p>0,05), three-vessel disease (p>0.05) and LM disease (p>0.05) among patients with coronary artery disea-se and without AF. Patients with persistent AF and coronary disease have significantly higher incidence of LCX (p<0.05) and RCA (p<0.01) than those without AF. There was no significant difference in the incidence of proximal segments of LCX (p>0.05) and RCA (p>0.05) between patients with and without AF with coronary artery disease. Conclusion: Three-vessel coronary disease, low ejection fraction left ventricle and secondary ischemic heart dise-ase followed by cardiac insufficiency are major factors contributing to the development of AF in stable coronary disease.
